Texas Winter 2024-2025

[Ntxw]

DFW catching up on the deficit of freezes for the winter. As of Jan 1 we were at just 1 (Dec 6th) versus normal of 10.5. We've strung together 10 in a row now, so we're at 11 versus a normal of about 16 through Jan 15th. Plenty of opportunities to catch up or get ahead over the next couple of weeks.

Early next week will easily be another 3-5, then the OPs and ENS are sending another big cold air mass to ending days of January, with a monster Alaskan ridge centered near or around the 28th.

Last January was the coldest since 2011, we may beat out January 2024.

Update for me. 00z Euro showed -17 Sunday am, -18 Monday am for my location.

We are going to be out of town for this cold snap, and I plan to turn the water off at the street. Do I need to do anything with the hot water heaters?

The Ice Man Cometh…get ready.

[CaptinCrunch]

Are you ready for some Football??

Houston @ Kansas City - 3:30pm 25 wc13
Washington @ Detroit - 7:30pm Dome non-factor
LA Rams @ Philadelphia - 1pm 35 wc26
Baltimore @ Buffalo - 4:30pm 26 wc12 40% chance snow


weather conditions may change by gametime

The low would have to reach the upper teens to lower 20s if we're talking above-freezing by noon. If the temperature would be 30F or lower for 24 hours, I'd shut it off. Our pipes are in the attic and they're not extremely well insulated. Temperature in the attic may be a degree or two warmer than outside air, though.

Why not just drip all faucets instead?

No guarantee that the very slowly running water won't still freeze in the pipes. What I did last January was stay up all night and turn on the hot water in the tap farthest from the water inlet (east bathroom). I'd let the hot water flow for a few minutes to get the pipes nice and warm. Our cold and hot pipes are attached side-by side in the attic. Running the hot water every hour or two would heat both pipes above freezing. That tactic won't work if your pipes are not next to one-another.

You have to understand that if the pipes in the attic DO freeze, they'll likely break in one or more areas. When they thaw, your house could be flooded. That brings up the need to be very clear on how to quickly shut off water to your house. On our house, there is a valve right on the hose bib that shuts off water entering the house. I shut that off and open all inside faucets to drain the pipes. Doing that is better than gambling on a flooded house.

Unfortunately, I don't have a cutoff valve close to the house. I have to cut it off at the meter (near the street). I agree with 57 though - better to shut off water to the house and drain the pipes to be on the safe side if a long duration period of sub-freezing temps is expected.

Omg..that’s amazing for SCTX…
I’ll believe it when I see.

Love that app. For browsing this forum and for reading models I still generally use my laptop as I am not a fan of Tapatalk etc., but man, that is a nice app.

Exciting to see some trends toward colder and wetter, but for the northern areas probably a small amount even with higher ratios.

Also, we should remember past events where the QPF shield starts off huge and then "shrinks" as we get closer, especially with a likely Gulf low.

I remember that storm in San Antonio in 1985. I was at Trinity University at the time and the tennis stadium roof collapsed.

Also high pressure on the Euro maps would probably get close to all time records for a few locations.

Anyone got graphics? My free sites are an hour away.

At what temps would you decide to shut off water to the house?

The low would have to reach the upper teens to lower 20s if we're talking above-freezing by noon. If the temperature would be 30F or lower for 24 hours, I'd shut it off. Our pipes are in the attic and they're not extremely well insulated. Temperature in the attic may be a degree or two warmer than outside air, though.

You run your faucets with a pencil led like thin stream. Got to keep the water moving is the key. Shutting off the will cause freezing of the piping system and will only make things worse upstream of your home where the water enters your home. Yes, this can possibly become a strain on the municipal water system if every homeowner does not adhere to a pencil lead thin stream. It is a fine line to adhere to. Everyone has to make their own call.

Well, that is an insane uptrend from the GFS

NWS already has mention of snow showers in their forecast for Monday in the city of Houston. They’re no weather app and never mention snow down here this far out…

Interesting that we were touting the GFS for leading the way, then the Euro caved, and then they all shifted to back to bigger western trough, while now the ICON is the other way.

A few extended range models are getting more aggressive with extending this pattern well into February....latest CFSv2 is Feb 2021 redux

First of all, don't just shut off the water, open all faucets and drain the water out of the lines. Leave the faucets open. That way, there can be no burst pipes. Second, running a thin stream of water SOUNDS like a good idea, until everyone else does the same thing and that thin stream shuts off in the middle of the night due to low water pressure. Upstream folks would not be impacted if you shut off your water, only if you let it run (they'll get lower pressure). I also have insulation that I put on faucet bibs and exposed piping.

Do you have any thoughts or experience with new builds in relation to outside temperatures in extremes? On our home, which is foam, it appears that the attic temperature is around 10 degrees warmer or cooler, but I wonder how it performs in extreme conditions.
